In continuous production for nearly 25 years, the MeriCal™ digital pressure transmitter calibrator is one of the most successful instruments to ever serve the process industries. Meriam's NEW M4 Series Handheld Precision Calibrator / Data Logger builds on this reputation with an impressive array of new features, functions and improved accuracy specification. The M400 includes one pressure sensor and one mA/V instrument. Choose from differential, gauge, compound or absolute pressure types and ranges from 10" H2O to 3000 PSIG full scale.

The M402 can be configured with any two gauges, compounds or absolute type sensors. Accuracy of ±0.025% of Full Scale is maintained over operating temperatures from -20° to +50° C (-4° to +122° F). Data Logging is standard on all models.

All M4 Series handhelds provide convenient electrical signal measurement and sourcing. Source or sink values are easily entered using the Adaptive Interface Wheel.
